Hi Mikhail,I attach both lspci for pci=nocrs and without pci=nocrs.
this is pretty clearly a problem with the system and/or it's BIOS and
not the GPU hw or the driver.
The option pci=nocrs makes the kernel ignore additional resource windows
the BIOS reports through ACPI. This then most likely leads to problems
with amdgpu because it can't bring up its PCIe resources any more.
The output of "sudo lspci -vvvv -s $BUSID_OF_AMDGPU" might help
understand the problem

but I strongly suggest to try a BIOS update first.This is the first thing that was done. And I am afraid no more BIOS updates.

I also have experience in dealing with manufacturers' tech support.
Usually it ends with "we do not provide drivers for Linux".
